The Apatosaurus specimen from the Museum's Hall of Saurischian Dinosaurs.

The biggest fossil dinosaurs I've ever found are sauropods from Central Asia as well as from the American West. These animals are related to the Apatosaurus and Mamenchisaurus. Mamenchisaurus is a giant sauropod from Central Asia. These plant-eating animals had fantastically huge, long necks and were the heaviest and longest dinosaurs ever found. Sauropods were the biggest animals ever to walk the earth.
